Power = Voltage x Current
P=V.I
Power (in Watts) = 110V x 8.70A = 957W (Appx. 1kW) - Neeraj Sharma

Do you split wattage on 2 pole breaker?
If the load is rated 220 or 230 or 240 volts (all the same thing), and specifies a wattage rating, that wattage rating is at the double pole voltage. You wouldn't make any adjustments to it. The load should also indicate the input current in Amps, which is used for sizing your breaker. If not, watts=amps x volts, so amps=watts/volts. For example, a 3800 Watt heater at 240v would require 15.83 amps. The breaker for this circuit would be 125 percent of that (safety factor), or 20 amps, 2 pole.
Vacuum is 1100 watts how many amps is that?
If running at 110V, that is 10Amps. Wattage = Voltage x Current Current = Wattage / Voltage - Neeraj Sharma
Is liners legal for cb radios?
In the US at least, no, linear amps are not legal for use on CB radios. The maximum wattage permitted for AM transmission is four watts, and the maximum wattage permitted for Single Sideband is 12 watts.
How many amps breaker you need for a 5000 watts immersion heater?
To answer this question the voltage of the immersion heater is needed. I = W/E.
What is the current through the 150 ohm heater?
At 110 volts it is 0.8 amps. At 220 it is 0.4 amps. I=E/R. I=amps.E=volts R=resistance.
How many amps do you need if you have a 480 volt space heater?
The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).
A 208V water heater can te be replaced by a 240V water heater?
Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.

How many amps are needed for a freezer?
You need to look at the rating plate on the freezer. My Kenmore upright freezer draws 5.0 A. Look for a number followed by the word amps or something like 5.0 A.
How many amps does a chandelier use?
The amperage that a chandelier draws is based on the amount of bulbs and the wattage of the bulbs used in the fixture. Count the amount of bulbs and multiply that number by the wattage of the bulbs. Take this total wattage and use this formula. I = W/E. Amps = Watts/ Volts.
What is the VA rating for common appliances?
For all intents and purposed the VA rating is the same as the wattage rating of appliances. VA is an electrical classification for Volt Amps. The formula for watts is, Watts = Amps x Volts.
Does a pool pump on 220 volts use the same amount of energy as a 110 volt?
Assuming it is also rated for 120V., yes. The wattage doesn't change with an increase or decrease in voltage. However, the current draw does. When you double the voltage a load is hooked up to, the Amperage draw (current) drops in half. Example: if a 240 volt heater draws 6 amps, it will draw 12 amps if connected to 120V. If a 120V heater draws 15 amps, it will draw only 7.5 amps when connected to 240V. But power, or wattage stays the same, regardless. And this is what is used to calculate energy usage and therefore, cost. Please note the above answer says "if it is also rated for"
How many btu in a 220 heater?
First you need to find out how many amps the heater draws. Then use this formula: Volts (220) X Amps = Watts Then take: Watts x 3.41214 = Btu/hr
Are electric baseboard heaters efficient?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
10kw heater at 220V draws how many amps?
45-50 amps. But your overcurrent protection and wire must be designed for 125% of load so the max overcurrent protection is 55 amps or 60
Can you run a 277volt heater on 220 volts?
Yes, you can but the wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts. W = watts, I = amperage, R = resistance in ohms and E = voltage.
